Power package with 7 Ampere

LÜTZE Transportation expands the Microcompact relay series to include a new powerful solid state relay for switching loads up to 7 amps.

Today many modern rail vehicles are equipped with a 110 V battery network. The problem: When switching inductive loads, mechanical relays often reach their technical limits very quickly. Whilst a conventional relay is able to switch an inductive load of around 0.2 A at 110 V, the new LÜTZE solid state relay is now able to switch inductive and ohmic loads up to 7 A. LÜTZE supplies the solid state relay in two versions: firstly, with a control voltage of DC 24-110 V and secondly with DC 72-110 V. The LÜTZE solid state relay can also be used with all standard voltages on rail vehicles. The LÜTZE 7 A solid state relay is designed according to all relevant rail standards such as EN 50155, EN 50121, EN 50124, EN 61373 and the European Fire Protection Standard EN 45545-2. Because of the very narrow width of just 12.5 mm, it can be used in all control cabinets.

The new LÜTZE solid state relay is protected against short circuits and over-heating on the output side. A status output and a status-LED indicate when a current flow exceeds 0.5 A. This means that a connected load with a broken wire can be monitored. The working temperature range of the solid state relay is -40°C to +70°C. The LÜTZE solid state relay is installed in a sturdy PC-ABS housing and therefore satisfies the European Fire Protection Standard EN 45545-2. The new solid state relay is suitable for mounting on DIN rails TS35. The 7 A solid state relay by LÜTZE Transportation supplements the 10 A relay for DC 24 V circuits that is supplied in the same housing.
